Abstract

The invention discloses a catalytic cracking catalyst for increasing diesel yield and a preparation method of the catalytic cracking catalyst. The preparation method comprises steps as follows: (1), raw materials and deionized water are mixed and beaten, and slurry is prepared; (2), the slurry is subjected to spray drying, and a product is roasted and washed; wherein the raw materials comprise non-boron phosphate type boron-containing substances, a molecular sieve, clay mineral and a fourth component with the binding effect. The catalyst has resistance to heavy metal pollution, high diesel yield is realized, and the preparation process is simple.

Description

technical field [0001] The invention relates to the technical field of catalysts for petroleum, in particular to the technical field of catalysts for catalytic cracking reactions of petroleum. Background technique [0002] At present, petroleum still occupies a major position in world energy consumption. An important and effective way of using petroleum is to refine gasoline, diesel, propylene, etc. through catalytic cracking reactions. 70-80% of gasoline, 30-40% of diesel, and 40-50% of propylene in my country's daily needs come from Catalytic cracking of petroleum. The degree of catalytic cracking, efficiency, and cleanliness of petroleum significantly affect the utilization rate of energy. [0003] The increasing demand for clean oil products worldwide has led to the trend of dieselization of internal combustion engine fuels. Compared with gasoline engines, diesel engines have many advantages such as high power, high fuel thermal efficiency, long service life, good star...
